:material-battery-plus: Optimizations
JELOS provides a variety of settings that allow you to optimize for battery life or performance globally, on a per system and per game basis. For emulating 6th generation and later systems, we recommend installing JELOS on internal storage if available to reduce IO bottlenecks reading and writing shader cache.
Optimizing For Performance
Optimizing for performance will have significant impact on battery life, however it will also provide the best experience for more demanding emulators.
